Travelling supporters had already booed England players taking the knee and held up a flag objecting to the anti-racism gesture ahead of kick-off, and were then tussling with police, who responded with batons in an attempt to restore order, within the opening five minutes.
A large group of officers appeared to have been forced out of the away end and onto the concourse by fans after engaging with them.
It comes after a string of incidents involving the nation’s supporters during the European Championships and in games since. UEFA have ordered Hungary to play a game behind closed doors following racist abuse from supporters and homophobic banners in the stands during their Euro 2020 group stage matches.
England’s players were then subjected to racist abuse by supporters during their 4-0 win in Budapest last month. Supporters were allowed to attend that game as it was under the jurisdiction of FIFA, but the Hungarian FA were subsequently hit with a 200,000 Swiss franc fine and a two-match stadium ban, with one of those suspended.
